Goin | December 9, 1997 |
A vacuum table system for assisting in the weeding of non-desired material from cut decal sheets is disclosed. A vacuum chamber having a perforated top is provided. A porous work surface is provided which communicates a vacuum present in the vacuum chamber to the surface of the work surface. Thus, objects placed on the work surface are held in place by the vacuum. A negative mask, corresponding to the desired portions of the decal, is placed on the work surface and the decal is aligned over the negative mask. The non-desired portions of the decal are drawn to the work surface by the vacuum from the peel-off paper backing while the desirable portions remain separated from the work surface by the negative mask. The decal is then lifted and the non-desired portions separate from the peel-off paper backing because of the vacuum. The desired portions remain on the paper backing due to their separation from the vacuum by the negative mask.
